BED-SPRING. l l

Patented Feb. 2o, 1906.

Application filed January 19, 1905. Serial No. 241,774.

`To @ZZ whom it may concern.-

Be it known that I, BENJAMIN F. LINDS- LEY, a citizen of the UnitedStates, residing at Mansfield, in the county of Richland and State ofOhio, have invented a new and useful Bed-Spring, of which the followingis a specification. i

My invention relates to a bed-spring composed of a series of conicalcoiled springs suspended in vertical series, in combination with aseries of coiled expansion or compression springs attached to each endof the frame on one end with the opposite ends secured alternately to abar and a chain which is used `to form part of the surface of thebed-spring.

In the construction of the ordinary bedspring now in use no provision ismade with reference to the fact that one or more persons or persons ofdifferent weight Will occupythe bed, the result being'that the tensionof the springs is either too weak or too strong to give the necessaryelasticity, which affords the comfort and rest the spring isdesigned toobtain;

The obj ect of my invention is to provide a meansof constructing abed-spring that will retain its elasticity uniformly when subjected toincreased or decreased weight and to afford facilities for maintainingthe elasticity when the wei ht is unevenly distributed on either side oft e spring.

A further object is to construct a spring in such a manner as to connectthe spring and chain to the frame, so as to give free movements to allof the parts formingthe surface and at the same time retaining them intheir proper positions.

' I attain these and other objects by the construction shown andillustrated in the accompanying drawings, in which- Figure 1 is atopplan view of my device, showing the conical and coiled springsattached, in combination with the chain to the frame which formsthe-surface of the bedsprng. Fig. 2 i's a side-view of Fig. 1, withdotted lines B B representing the center of the frame, showing the barupon which the conical springs are mounted and broken sections of theside rail. Fig. 3 is a top and side view of the linked brace-bar,showing method of tying and retaining the spring -bars in place. Fig. 4is a bottom plan view of one conical spring, showing loop in spring withthe free end hooked therein, forming a complete circle. Fig. 45 is a,side plan view of one to the coil-springs 6.

of the coiled sprin s. Fig; 6 is a view of a broken section of t e chainused to form the surface of the bed-spring. Fig. 7 is a side plan viewof one of the conical springs, showing means of fastening the spring tothe bar, whereby free movement is given to the spring. Fig. 8 is a sideview of one of the side rails.

Similar figures of reference refer to similar parts throughout theseveral views.

In constructing my device I provide 4a frame consisting of end pieces 1and side rails 2. The end pieces are notched, permitting them to rest onthe end and side rails of the bed when used in conjunction with anordinary iron bed. Bars 3 are securely fastened to the end pieces 1,leaving part of the bars projecting inwardly. Apertures 4 are providedto receive the looped ends 5 of the coiled expansion or compressionspring 6. Depending bars 7, having apertures in each end, are attachedto the opposite end or loop of the coiled spring 6. ed to support theconical springs 8. T e bars are formed so as to leave the bottom of .thesprings projecting more or less above the plane of frame. One end 9 ofthe conical spring is formed L-shaped and inserted in a suitableaperture 10, provided in the bar 7. It will be noted that this method offastening the springs to the bar retains the springs securely and at\the same time permits free movement of the connecting parts, obv'iatinundue friction, which aHects theelasticity o the bed-spring. A suitablelinked chain 11, preferably of kind shown in Fig. 6, is attachedA'alternately to the coil-springs 6a through the medium of the rings 12.are connected to the ends of the'chains 11 and the rings 12, which inturnare connected Chains 11El in broken sections are connected to theconical 'springs and the auxiliary chains 13, forming part of thesurface of the bed-spring. Chains 13a are provided to complete thesurface of the bed-spring. The ends of llware connected to the top ofeach conical spring' at points diametrically opposed to each other andserve to keepthe spring in proper position and counteract the tendencyof spring to move endwise.

-Side bars 14 are connected to the end pieces 11 of the frame throughthe medium of the coil-springs 15, which connect them under tension forthe purpose of preventing any The bars 7 are adatj Auxiliary chains 13the broken chain -mounte of novel brace 18, Which is composed of a vinttendency of the spring to move sidevvise when the springs are underpressure. Short sections 16 of alinked chain are connected to the topofthe conical springs at right angles to the chains 11 and 11a \toprevent side or lateral motion. The end sections 17 of the chain 16 areconnected to the side bars 14.

'In 'order to hold the bars 7 in proper alinement u on Which theconical' springs are I connectthem together by means ment of eaeh othe:`and of the coiled springs attached to the end pieces. The end springssupport a predetermined amount of the Weight, and when theWeight isincreased two y conical springs supportthe additional Weight withoutaffecting the elasticity of the bedsprings. The entire bed-s ring issuspended from the end pieces bytlie bars and chain, and all parts havevfree and' independent movement in relation to each other.

Slight changes and modifications can be made Without deviating from theprincipal involved lin my invention.

What I claim as my invention, and desire to secure by Letters Patent,is-

' y1. In a bed-spring the combination of a frame having a series of barssuspended from end pieces, a series of conical springs mounted on saidbars, coil-s rings securely attached to the end pieces, c ains connectedto said s rings substantially as and for the'purp'ose escrlbed. Y

2. In 'a bed-s ring composed of a frame having suitable Bars suspendedtherefrom, a. series of-coile'd springs attached't'o'said frame, chainsattached to said coiled springs through thel medium 4of suitable rings aseries of short; sections of chain connecting the top of the conicalsprings at points diametrically opposed to each other with the ends ofsaid sections secured to suitable side bars.

3. The combination of a frame having deending tubular side rails, Withend pieces i aving their corners notched-and 'adapted to iitthe end andside railsof the bed, side bars connected tothe end pieces under tensionthrough the medium of coiled springs.

4. Ina bed-spring composed of a frame having suitable bars attachedthereto and projecting inwardly with apertures provided therein andadapted to receive the loo ed end of the coiled springs, rings attacheto the opposite looped ends of the coiled springs, c ains connectedthereto and adapted to form part of the surface of the bed-springs, saidchainst and springs being adapted -to maintain a'predetermined Weight, aseries of bars suspended from the end pieces and supported by coiledsprings attached thereto, a series of conical springs adapted to besupported vertically from said bars whereby additional Weight issustained Without affecting the elasticity of the bed-spring.

5. In a bed-spring the combination of a framehaving a series of coiledsprings attached horizontally to the end pieces thereof,

said springs supporting a series of bars, a se, ries of conical springsmounted thereon, a linked brace connecting said bars together wherebysaid springs are kept in proper alinement permitting independentmovement substantially as and for the purpose described.

6. In a bed-spring the combination of a frame havin springsattac edthereto, a series of bars suspended from said frame, chains supported bysaid coiled springs, a series of conical s rings supported by said bars,side bars attac ed to the end piece of the frame under tension andadapted to prevent lateral motion, chains attached to alternate coiled srings forming Ya part of the surface of the be -spring 7. In abed-spring the combination of a `frame having a series of coiled springsattached thereto, a series ,of bars sus ended therefrom, conical s ringssupported ysaid bars, chains secure ,to said coiled springs, side barssecured to sections of said chains in such a manner as to give free andinde endent movementto all parts substantially as -and for the urposedescribed.
